具有交叉训练的多服务台多类排队系统的遍历控制问题

An ergodic control problem for many-server multiclass queueing systems with cross-trained servers

Anup Biswas

摘要:

AM/M/N+在Halfin-Whitt机制中,考虑独立的客户类和d个服务器池。第i类客户具有池i中的服务的优先级,其中i = 1,. . .、d,并且如果某个其他池有空闲服务器并且池i中的所有服务器都很忙,则可以访问该池。我们建立了一个遍历控制问题,其中运行成本由多项式增长的非负凸函数给出。我们表明,限制受控扩散模型的动作空间,它取决于状态变量。我们对极限遍历控制问题进行了完整的分析,并建立了排队模型的值函数的渐近收敛

英文摘要:

AM/M/N+Mqueueingnetworkisconsideredwithdindependentcustomerclasses and d server pools in Halfin-Whitt regime. Class i customers has priority for service in pool i for i = 1, . . . , d, and may access some other pool if the pool has an idle server and all the servers in pool i are busy. We formulate an ergodic control problem where the running cost is given by a non- negative convex function with polynomial growth. We show that the limiting controlled diffusion is modeled by an action space which depends on the state variable. We provide a complete analysis for the limiting ergodic control problem and establish asymptotic convergence of the value functions for the queueing model
